The package health checker

---

Are your projects' dependencies well maintained? Do they have good community support? How about their levels of popularity or security issues? Inspired by and built on top of Snyk Advisor, Dependescope scans repository packages health status and returns pass/fail results against threshold settings. Scan your projects today and discovery if they meet your expectations for overall health!

Tool features include:

• Stand alone/CLI python file
• CI/CD pipeline friendly
• NPM (package.json) and PYPI (requirements.txt) support
• JSON or Standard output

Installation

git clone https://github.com/dhammon/Dependescope
cd dependescope
pip3 install -r requirements.txt
